From: Eustachian tube dysfunction in patients with house dust mite-allergic rhinitis
After 1 month of treatment in HDM-allergic rhinitis patients, improvements in nasal condition affect recovery from eustachian tube dysfunction (ETD). Nasal symptoms of itching (a), sneezing (c) and rhinorrhoea (d) were not significantly different between the controlled-ETD group (ETDQ-7 score < 15 after treatment) and the uncontrolled-ETD group (ETDQ-7 score ≥ 15 after treatment). The VAS scores for nasal obstruction (b) and the nasal endoscopic scores (e) were higher in the uncontrolled-ETD group than in the controlled-ETD group (p < 0.01)
